Calculates the square root of the specified double-precision floating-point data
(64 bits) and outputs the result to the result words.
S
R
Calculates the natural (base e) exponential of the specified double-precision
floating-point data (64 bits) and outputs the result to the result words.
S
R
Calculates the natural (base e) logarithm of the specified double-precision float-
ing-point data (64 bits) and outputs the result to the result words.
S
R
Raises a double-precision floating-point number (64 bits) to the power of
another double-precision floating-point number and outputs the result to the
result words.
B
E
R
Compares the specified double-precision data (64 bits) and creates an ON exe-
cution condition if the comparison result is true.
Three kinds of symbols can be used with the floating-point symbol comparison
instructions: LD (Load), AND, and OR.
